Answer:
The angles of every triangle add up to 180
Step-by-step explanation:
Angle 2=52) Add 71+57=128. 180-128=52
Angle 1= 123) Angle 57 and 1 are supplementary angles which means they add up to 180. So subtract 57 from 180 which will give you 123.
Angle 3= 29) Now that we know that angle 1 is 123, we add 123 and 28 which gives 151. Then subtract 180-151 which equals 29.
This problem was like a pattern. You work with one part at a time and then you unsolve each part :)
The angles in the triangle are as follows;
∠1 = 117 degrees
∠2 = 52 degrees
∠3 = 35 degrees
How to find the angles in a triangle?A triangle is a polygon with three sides . The sum of angles in a triangle is 180 degrees.
The angles can be found as follows in the triangle.
∠1 = 180 - 57 = 117 degrees(sum of angles in a triangle)
∠2 = 180 - 71 - 57(sum of angles in a triangle)
∠2 = 52 degrees
∠3 = 180 - 28 - 117
∠3 = 35 degrees

Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
x - 2y = 6
y = 11 - 3x
Step 2: Rewrite systems
Define: x - 2y = 6Add 2y on both sides: x = 2y + 6x = 2y + 6
y = 11 - 3x
Step 3: Solve for y
Substitute in x: y = 11 - 3(2y + 6)Distribute -3: y = 11 - 6y - 18Combine like terms: y = -6y - 7Add 6y on both sides: 7y = -7Divide 7 on both sides: y = -1Step 4: Solve for x

Answer:
3 1/8 inches
Step-by-step explanation:
For focus-vertex distance p, the equation of the parabola can be written ...
y = x^2/(4p)
Here, we have p=8. We want to find the value of y when x=10 (the radius of the dish). That is ...
y = (10^2)/(4·8) = 100/32 = 3 1/8

Sharon drove 270 miles in 4.5 hours. If she drove at a constant rate, how fast was Sharon driving?
Answers
Answer:
Sharon was driving 60 miles per hour.
Step-by-step explanation:
To solve this you must divide both the amount of miles (270) and the amount of hours (4.5) by the amount of hours so that way you can see how many miles per hour you are going.
4.5 / 4.5 = 1
270 / 4.5 = 60
This means that Sharon was driving 60 miles per hour.

Grace wants to frame a square picture which has a area of
950 square inches.
How long is each side of the picture?
She has another square picture with an area of 1200 square inches.
How long is each side of this picture?
Answers
Answer:
First Picture: Length = 30.82in
Second Picture: Length = 34.64in
Step-by-step explanation:
Given
Picture 1:
Area = 950in²
Picture 2:
Area = 1200in²
Required
Determine the length of each pictures
From the question, we understand that both pictures are square in shape and the area is calculated as thus:
Area = Length²
For the first picture, substitute 950 for Area
This gives:
950 = Length²
Length ² = 950
Take square root of both sides
Length = √950
Length = 30.8220700148448822
Length = 30.82 (approximated)
Hence, the length of the first picture is 30.82in
For the second picture, substitute 1200 for Area
This gives:
1200 = Length²
Length² = 1200
Take square root of both sides
Length = √1200
Length = 34.6410161513775458
Length = 34.64 (approximated)
Hence, the length of the second picture is 34.64in

Mr. Smith's wife works at an animal hospital. There is a equivalent fraction relationship between the number of dogs and cats in the kennels. If there are 20 cats in the kennels, how many dogs?
Answers
Answer:
There are 10 dogs in the kennels
Step-by-step explanation:
The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.
Which means, if [tex]n_d[/tex] the number of dods and [tex]n_c[/tex] is the number of cats, then,
[tex]\frac {n_d}{n_c}=\frac{1}{2}\cdots(i)[/tex]
Given that there are 20 cats, so [tex]n_c=20.[/tex]
Now, from equation (i) we have,
[tex]\frac {n_d}{20}=\frac{1}{2}[/tex]
[tex]\Rightarrow n_d=\frac{1}{2}\times 20[/tex]
[tex]\Rightarrow n_d= 10[/tex].
Hence, there are 10 dogs in the kennels.
